State recommends '04 corn hybrids

The official list of corn hybrids recommended by the LSU AgCenter for production in 2004 is out and will be posted on the Internet soon. This year, we had 87 entries, the largest number entered into the trials thus far. As expected, most of the hybrids that did well in the corn demonstrations across the state are included in the recommended list.

For the recommended hybrid list, there are two categories regarding days to maturity: early at 100 to 110 days and medium at 111 to 120 days. There is usually a full-season category, which is 121 days or more, but no hybrids that were recommended fell in that category this year.

The list below includes all recommended hybrids (not differentiated by recommendation per location) with their respective two-year mean over locations, including the 2002 and 2003 growing years.

In addition to the recommended hybrid list below (two-year mean over locations with yields in bushels per acre), I have added a few comments on select hybrids that stood out in demonstrations as well as in the variety trials across the Louisiana.

Early maturity: Pioneer 34B23, 139 (bushels per acre); N65-M7, 140.

Medium maturity: DeKalb DK697, 148 (bushels per acre); DeKalb DKC68-70 YGCB, 142; DeKalb DKC69-70 YGCB, 151; DynaGro 5515, 142; DynaGro 5518, 141; DynaGro 58K22, 144; DynaGro 57K66, 135; Garst 8230 IT, 145; Garst 8288, 144; Genesis 2A16 RR, 141; Genesis 2A16 YG, 148; Genesis 2B16 TR, 143; Genesis 3214 YG, 144; Golden Acres 2995 RR, 145; Golden Acres 8112, 139; N83-N5, 141; N83-Z8, 147; Pioneer 31B13, 153; Pioneer 31G98, 149; Pioneer 31R88, 150; Pioneer 32D99, 156; Pioneer 32R25, 151; Pioneer 32W86, 147; Southern States 859 CL, 144; Terral 2130, 142; Terral 2140, 141; Terral 2140nRR, 143; Terral 2155 Bt, 138; Terral 2160Bt, 147; Terral 23R15n, 140; Terral 24R10, 138; Terral 26BR10n, 145.

Pioneer 32R25: 116-day hybrid, high yielder with exceptional drought tolerance and earlier maturity.

Pioneer 31B13: YG 119-day hybrid, one of top-yielding hybrids in the state in the past couple of years, excellent yield potential and drought tolerance and good plant height.

Pioneer 31R88: 120-day hybrid, has done very well in a wide range of environments.

Pioneer 32D99: 118-day hybrid, excellent yield potential, and has done very well in the yield trials in the past couple of years.

Terral 2140nRR: 113-day hybrid, excellent yield potential as well as being adapted to a wide range of soil types.

Terral 2160Bt: 115-day hybrid, superior yield potential, excellent drought-stress tolerance, and excellent shuck coverage.

Terral 26BR10n: 115-day hybrid, excellent standability and yield potential in addition to being YG and RR.

Dekalb 697: 119-day conventional hybrid, excellent yielder, reported as one of the more aflatoxin tolerant hybrids.

Dekalb 69-70 YGCB: 119-day hybrid, has done very well across a wide range of locations in the state.

Dyna-Gro 5518RR and 58K22RR: 118-day hybrids, have done well and have excellent test weights, husk coverage, best suited for irrigated situations.

Garst 8288: 116-day hybrid, good yield potential with excellent dry-down potential, tall hybrid.

N83-N5: 117-day hybrid, does best on highly productive soils, has been doing well across the state for a few years.
